What's your view on the recent RT-X efforts/scaling via IL?

With recent RT-X efforts from Deepmind, it seems the community has been shifting towards the development of a more generalized foundational model, combining with visions and languages, and scaling via imitation learning. I know RL algorithms are expensive to train and hard to scale due to the way the samples are generated, but I am still fascinated by the intelligence behind their philosophies. What do you think the future would look like? Like NLP or CV, having a big foundational model pre-trained via IL, and fine-tune on different tasks via RL? How can we tell if a task is simple enough that we don't need to leverage the power of a foundational model? submitted by /u/Old_Reading_669 [link] [comments]

Implementing Gradient Descent in PyTorch

The gradient descent algorithm is one of the most popular techniques for training deep neural networks. It has many applications in fields such as computer vision, speech recognition, and natural language processing. While the idea of gradient descent has been around for decades, it’s only recently that it’s been applied to applications related to deep […] The post Implementing Gradient Descent in PyTorch appeared first on MachineLearningMastery.com.

Training a Linear Regression Model in PyTorch

Linear regression is a simple yet powerful technique for predicting the values of variables based on other variables. It is often used for modeling relationships between two or more continuous variables, such as the relationship between income and age, or the relationship between weight and height. Likewise, linear regression can be used to predict continuous […] The post Training a Linear Regression Model in PyTorch appeared first on MachineLearningMastery.com. ( 24 min )

Making Linear Predictions in PyTorch

Linear regression is a statistical technique for estimating the relationship between two variables. A simple example of linear regression is to predict the height of someone based on the square root of the person’s weight (that’s what BMI is based on). To do this, we need to find the slope and intercept of the line. […] The post Making Linear Predictions in PyTorch appeared first on MachineLearningMastery.com. ( 21 min )

Loading and Providing Datasets in PyTorch

Structuring the data pipeline in a way that it can be effortlessly linked to your deep learning model is an important aspect of any deep learning-based system. PyTorch packs everything to do just that. While in the previous tutorial, we used simple datasets, we’ll need to work with larger datasets in real world scenarios in […] The post Loading and Providing Datasets in PyTorch appeared first on MachineLearningMastery.com.

Using Dataset Classes in PyTorch

In machine learning and deep learning problems, a lot of effort goes into preparing the data. Data is usually messy and needs to be preprocessed before it can be used for training a model. If the data is not prepared correctly, the model won’t be able to generalize well. Some of the common steps required […] The post Using Dataset Classes in PyTorch appeared first on MachineLearningMastery.com. ( 21 min )

Two-Dimensional Tensors in Pytorch

Two-dimensional tensors are analogous to two-dimensional metrics. Like a two-dimensional metric, a two-dimensional tensor also has $n$ number of rows and columns. Let’s take a gray-scale image as an example, which is a two-dimensional matrix of numeric values, commonly known as pixels. Ranging from ‘0’ to ‘255’, each number represents a pixel intensity value. Here, […] The post Two-Dimensional Tensors in Pytorch appeared first on Machine Learning Mastery. ( 21 min )

My family's unlikely homeschooling journey

My husband Jeremy and I never intended to homeschool, and yet we have now, unexpectedly, committed to homeschooling long-term. Prior to the pandemic, we both worked full-time in careers that we loved and found meaningful, and we sent our daughter to a full-day Montessori school. Although I struggled with significant health issues, I felt unbelievably lucky and fulfilled in both my family life and my professional life. The pandemic upended my careful balance. Every family is different, with different needs, circumstances, and constraints, and what works for one may not work for others. My intention here is primarily to share the journey of my own (very privileged) family.

The Jupyter+git problem is now solved

Jupyter notebooks don’t work with git by default. With nbdev2, the Jupyter+git problem has been totally solved. It provides a set of hooks which provide clean git diffs, solve most git conflicts automatically, and ensure that any remaining conflicts can be resolved entirely within the standard Jupyter notebook environment. To get started, follow the directions on Git-friendly Jupyter.
